Product Description
The RCQ-1 Electrical Resistivity Tomography Equipment is a modern, high-precision logging instrument designed for formation resistivity measurement in oil, gas, and geological exploration. Using classic AB–MN electrode configuration with optimized micro-gradient and micro-potential systems, it delivers clear, stable resistivity curves for identifying lithology, fluid content, thin layers, and structural changes. Compact, reliable, and easy to operate, the RCQ-1 is suitable for professional geophysical survey teams seeking accurate subsurface electrical imaging.
As a specialized instrument, the RCQ-1 Electrical Resistivity Tomography Equipment focuses solely on apparent resistivity and SP measurement. It is not intended for expansion with third-party or multi-parameter probes.

Working Principle & Advantages
The RCQ-1 Electrical Resistivity Tomography Equipment transmits adaptive AC square-wave signals into the formation and simultaneously monitors both injected current and return voltages. Its measurement architecture ensures broad dynamic range, stable readings, and high reliability even in deep, complex boreholes.
To ensure accurate SP logging, the instrument includes a power-off AB potential mode, effectively reducing interference from artificial electrical fields and improving natural potential stability.
The dual-channel voltage acquisition system enables the recording of gradient resistivity + potential at the same time, improving data richness without extending logging time.

Streamlined deployment and operation, reducing setup time in field environments
Dual-channel voltage acquisition, enabling simultaneous gradient and potential curve logging
High measurement stability and repeatability, suitable for layered or complex formations
Integrated processing software for rapid curve generation, visualization, and interpretation

FAQ
1. What types of boreholes can RCQ-1 Electrical Resistivity Tomography Equipment be used in?
The equipment is suitable for water wells, geological exploration boreholes, engineering investigation holes, and most vertical or slightly inclined boreholes with stable wall conditions.
2. How deep can the probe be deployed?
Deployment depth depends on the cable length you choose. Standard configurations support 300–600 meters, and customized lengths are available based on project requirements.
3. Is the Electrical Resistivity Tomography Equipment difficult to operate for first-time users?
No. The equipment comes with an operation manual, step-by-step software guide, and online technical training. Most users can complete basic logging independently after a short practice session.
4. What kind of data does the instrument record?
It records apparent resistivity and SP (natural potential) data. Dual voltage channels allow collection of two curves simultaneously for improved efficiency.
5. What after-sales support do you provide?
We offer remote technical support, troubleshooting assistance, software updates, and long-term spare-parts supply to ensure reliable operation throughout the equipment's service life.
